The smart grid in the future will definitely develop towards new energy. The world's resources are limited, we can only look for more clean energy, solar energy, wind energy, electric energy, etc. will be the emerging electricity in the future.
The advice that the smart grid may give you in the future is also our vision for the future development of the industry. With such a wonderful life, why don't we learn more about it now? A few days ago, the 2017 Beijing International Wind Energy Conference and Exhibition and the 2017 China Photovoltaic Conference and Exhibition were held in Beijing, and the intelligence and digitalization of the industry became one of the hot topics at the conference. In addition to discussing the disruptive vision that can be realized by intelligence and digitalization, the meeting also mentioned the progress that the industry has made in the context of the energy revolution. For example, through lidar, wind turbines can already sense the speed and direction of incoming wind in advance, so as to execute better strategies.
Look, the wind is coming, and now even wind turbines can see this for themselves.
The de-subsidyization of wind power and photovoltaics has become a trend, and the new energy industry is already at a critical stage of independent survival and industrial upgrading. At this time, the tool "digitization" is believed to help renewable energy industries such as wind power and photovoltaics break the current cost ceiling and improve the efficiency of the energy system. What is even more imaginative is that some people in the industry have seen that the digital energy Internet will transform energy service providers from a "selling energy" model to a "selling service" model.
This trend is not on paper. Manufacturers of complete machines and accessories, including Trina Solar, Goldwind (002202, SZ), and Sungrow (300274, SZ), are exploring digitalization; while traditional energy service providers Siemens, Third-party companies, including the communications operator Huawei, have also deployed the digitalization of the renewable energy industry.
Digitization helps new energy to be connected to the Internet at a parity
From October 17th to October 19th, the 2017 Beijing International Wind Energy Conference and Exhibition and the 2017 China Photovoltaic Conference and Exhibition were held in Beijing. At the meeting, the topic of reducing costs for wind power and photovoltaics through digitalization attracted attention.
This year, the development of the photovoltaic industry was unexpected. After the "6.30 rush to install", its development momentum has not diminished. Wang Bohua, Secretary-General of China Photovoltaic Industry Association, said at the 2017 China Photovoltaic Conference and Exhibition that the photovoltaic industry has grown significantly this year in terms of manufacturing, and the application side has expanded strongly.
A set of data brought by Zhang Zhengling, deputy director of the Development Planning Department of State Grid Corporation of China, shows that as of the end of June 2017, the cumulative installed capacity of wind power and solar power has reached 154 million and 102 million kilowatts, both exceeding 100 million kilowatts. Gansu has become the largest power source.
When the wind power and photovoltaic industry has developed to such a scale, how to effectively reduce costs and ultimately achieve affordable Internet access has become the focus of all parties, and digitalization, intelligence, and the Internet of Things have become an important direction.
At present, power station operators above designated size have generally established their own data systems, which play an important role in energy operation. So how do these systems work?
Qiu Zhanwei, chairman of Zhejiang Chint New Energy Development Co., Ltd., told reporters that for ground power stations and industrial and commercial power stations, the monitoring platform can predict abnormalities, reduce losses, and effectively increase power generation.
Zeng Weisheng, vice president of Huawei's network energy product line and general manager of the Smart Photovoltaic Business Department in China, said that the improvement of Internet of Things technology, communication technology, information technology and the Internet will definitely reduce costs and improve efficiency.
Zhao Wei, vice president of Sungrow, also mentioned in an interview with reporters that digitalization can monitor the status of power station equipment more precisely, which has a great effect on the operation and maintenance of power stations. Especially in the future, the power grid will require that each power station is fully controlled, and digitalization can accurately know the status of the power station.
Energy Internet has more imagination
From enterprise users to individual household users, from a single application such as a rough meter reading electricity bill to a smart grid that can comprehensively monitor the operating conditions of enterprises or households, Li Furong, Assistant General Manager of Goldwind R&D Center, talked about future applications such as wind power and photovoltaics There are a lot of emotions in the scene. In his eyes, the smart grid can detect changes in indoor voltage and the usage of electrical appliances in real time, and even recommend electrical appliance brands to users.
In the eyes of people in the wind power and photovoltaic industries like Li Furong, the roof of every home can become a power station, and everyone can participate in the decentralized energy system. Every device and every home will be connected to truly realize the goal of energy interconnection of power generation, energy storage, distribution and consumption.
The capital side has long realized the opportunity for new energy to "connect to the Internet". At the industry conference held recently, multinational companies, including established energy service providers such as Siemens, and Internet communication companies such as Huawei, have already deployed.
Hong Zemi Road (Shanghai) Investment Consulting Co., Ltd. mentioned in the research report that traditionally, industrial giants such as GE, Siemens, and Schneider Electric have provided efficiency management solutions. Enter the energy management market and grab market share.
Although wind power and photovoltaics have gradually penetrated from the upstream equipment manufacturing of the industry to the downstream power station operation, there is still a long way to go before the digital scenario envisaged above.
Zhao Wei said that digitalization has just begun, and now power generation is power generation, which is relatively isolated, and digitalization is still relatively shallow. It mainly stays at the equipment level such as maintenance and operation management, and needs to be further refined. In the future, digitalization will play a key role in the combination of photovoltaic and wind power with energy storage, and whether the characteristics of photovoltaic power plants or wind farms can be comparable to those of thermal power. Zhao Wei believes that in about ten years, many application scenarios of the above-mentioned energy Internet will appear.
And Zhuang Yan, chief commercial officer of Canadian Solar Group, told reporters, "(Energy Internet) is coming sooner than you think." He believes that traditional energy is facing the huge impact of wind power and photovoltaics, when wind power, photovoltaics and thermal power, etc. When combined to provide a solution for users, the Internet of Energy must emerge.
